News From the national conference!
Hey team!! We are promoting this national campaign that will affect us all in some way. Would you please “like” this page- We are trying to get interest rates reduced for graduate and professional students by almost half. This would save the average student $200 per month, $2400 per year in extra interest that you will pay after graduation. As of now, for every dollar you borrow, you will pay back $1.40 to the government. This year total interest on cumulative graduate loans will make the government more profit than Apple this year!! — thanks for your help and please send this to your friends if you want lower interest rates!

Additionally, here you will find a national survey compiling data about student stipends, fees, and health insurance.
